I think we all agree the 4.2 is a better engine.
That's not an issue.
If you are starting from scratch,dont have an engine,by all means,go w/the 4.2,it will make more power ,it will be different,pretty sure it's lighter than a 250?
I said it before,if I did not have all the parts for my 250,I would go that way also,,but I am stuck w/the 250 for the time being,but I like the old school engine & if I can run 9's in a street car ,all the better.
